12.1‐inch 169‐ppi full‐color micro‐LED display using LTPS‐TFT backplane has been successfully developed. Blue micro‐LED, whose size is less than 30 mm, was applied with red and green conversion materials to produce full‐color images. Contrast ratio of >1,000,000: 1 with brightness of 700 nits was realized by the full‐color micro‐LED display for high‐dynamic‐range display applications.

Flexible substrate materials and handling method are the key factor for flexible liquid crystal displays (LCDs). A 3.47 inch flexible LCD designed for wearable applications was successfully fabricated using an optical clear fiber-reinforcedplastic (FRP) substrate and a film lamination followed by mechanical peeling process. This is the first flexible liquid crystal display applied for wearable smart device

In this paper, a 65‐inch blur‐free transparent LCD was presented. A simple way of controlling LC orientation was applied to suppress the issue of blurry images behind transparent LCD. Furthermore, the individual controllable RGBW sub‐pixels were used to improve the transmittance and realize the hybrid transparency on the display.

In this paper, a novel transparent light guide has been developed. Concave microstructures with partially random distribution were designed to reflect incident light and prevent moiré issue. Furthermore, a 12.1‐inch RGBW LCD was combined with the transparent light guide to demonstrate the transparent tablet scenario.

In this paper, a 10.1" color filter-less liquid crystal display (LCD) with transparent light guide has been developed for transparent LCD (T-LCD) application. LED light sources could create four primary -color fields R-G-B-W rapidly flashing to satisfy field-sequential-color (FSC) method. Finally, this prototype could demonstrate a high NTSC and transparency scenario.
